ABSTRACT

OBJECTIVE@#To explore clinical effects of repairing skin and soft tissue defect of finger with free posterior interosseous artery perforator flap.@*METHODS@#Totally 8 patients with finger skin and soft tissue defect repaired with free posterior interosseous artery perforator flap were treated from May 2021 to November 2022, including 7 males and 1 female aged from 24 to 54 years old, and soft tissue defect area ranged from 3.0 cm×1.5 cm to 5.0 cm×3.0 cm. The time from injury to flap repair ranged from 3 to 83 h. The free posterior interosseous artery perforator flap was applied to repair finger defect, the area of the flap ranged from 3.5 cm×2.0 cm to 5.2 cm×3.5 cm, the donor area of flap was sutured directly. The survival, appearance, texture and donor complications of the flap were observed after operation, and Dargan functional standard was used to evaluate clinical effect of finger function.@*RESULTS@#All flap of 8 patients were survived, and followed up from 3 to 12 months. There was no obvious swelling, soft texture, obvious pigmentation, linear intaglio in donor area only, and without obvious complications were found. Among them, 3 patients'skin flaps were repaired for the defect of palm of the fingers, and sensory recovery was good, two-point discrimination ranged from 5 to 9 mm. According to Dargan functional evaluation, 3 patients excellent, and 5 good.@*CONCLUSION@#Free posterior interosseous artery perforation branch flap could be used to repair the defect of finger. The thickness of flap is moderate, operation is convenient, appearance and texture of the operative flap are good, and the donor site is small without obvious complications, and obtain satisfactory clinical effect.

ABSTRACT

OBJECTIVE@#To explore method and clinical effect of microsurgical thinned anterolateral thigh perforator flap to repair soft tissue defects of foot and ankle.@*METHODS@#From March 2017 to January 2022, totally 20 patients with soft tissue defects of ankle joint were treated with micro-thinning anterolateral perforator flap for free transplantation, included 13 males and 7 females, aged from 22 to 58 years old with an average of (36.45±12.36) years old. The size of flap ranged from 8.0 cm×5.0 cm to 20.0 cm×12.0 cm. Before operation, perforating vessels on the anterolateral thigh region were detected and marked with a portable Doppler detector. For the defect width less than 8 cm, 11 patients were repaired with a single flap. For the defect width more than 8 cm, the wound could not be sutured directly, and the lobulated flap technique was used in 9 patients, the width was converted to length, and the donor site was closed directly. Under the microscope, all flaps were thinened in a stepwise manner from the center of the pedicle to the periphery. After operation, survival of the flap, the shape, texture, sensory function recovery were observes, and recovery of foot function was evaluated by Maryland foot function evaluation standard.@*RESULTS@#All 20 patients with microsurgical thinned anterolateral thigh perforator flaps were survived. Venous crisis occurred in 1 patient due to subcutaneous hematoma, after removal of the hematoma, the crisis was relieved and the flap survived successfully. The wounds in the donor and recipient sites healed well, and only linear scars left in the donor sites. Twenty patients were followed up for 3 to 26 months after operation, good shape of flaps without bloated, and good texture. The two-point discrimination of free flaps ranged from 9.0 to 16.0 mm, and the protective sensation was restored. The ankle flexion and extension function recovered well and patients could walk normally. According to Maryland foot function evaluation standard, 8 patients got excellent result, 10 patients good and 2 middle.@*CONCLUSION@#Microsurgical thinned anterolateral thigh perforator flap is an ideal method to repair soft tissue defects in functional area of foot and ankle, with good appearance and texture of the flap, no need for re-plastic surgery, reduced hospitalization costs, and less donor site damage.

ABSTRACT

Objective To evaluate the effectiveness of the comprehensive intervention program of Xinjiang and to analyze the main problems to provide references for the adjusting on the intervention strategies in future work.Methods Based upon the combination of reviewing literatures,field investigations and questionnaires,an overall evaluation was made on the effectiveness of the program,supportive policies and intervention measures,etc.Results Some progressions had been achieved in the early days.However,in recent years,the negligence of the work and failed coordination between the related governments,and unbenefitting policies for iodinated salt,were the main obstacles for the progress.Conclusions To improve the progress of controlling iodine deficiency disorders,the government should fully carry on its responsibility,giving supports both of policy and funds.Salt administrative sector should make favourable policies to benefit the local population.And health sector should coordinate the related sectors,and reinforce the health education and surveillance.

ABSTRACT

<p><b>OBJECTIVE</b>To study the relationship between the expression of dipeptidyl peptidase IV (DPP IV) gene and malignant behavior of cells of ovarian carcinoma.</p><p><b>METHODS</b>The differences of the malignant behavior of A2780, SKOV-3, HO-8910 and HO-8910PM cell lines were examined by drawing cell proliferative curves, adhesive test, assay of incursion and chemotaxis. The expression of DPP IV among the cell lines and its relationship with the malignant behavior of ovarian carcinoma cell were detected by techniques of DPP IV activity assay, cytometry and reverse transcription polymerase chain reaction.</p><p><b>RESULTS</b>Among all cell lines, the ability of proliferation, adhesion, incursion and chemotaxis of HO-8910PM were the highest, while those of A2780 were the lowest. The transcription of mRNA in A2780, SKOV-3, HO-8910 and HO-8910PM cell lines were 0.7512 +/- 0.0012, 0.5596 +/- 0.0015, 0.3369 +/- 0.0009, and 0.2777 +/- 0.0006, respectively. The activity of DPP IV were 0.79 +/- 0.02, 0.64 +/- 0.03, 0.21 +/- 0.02, and 0.18 +/- 0.01, respectively; and the protein expression of DPP IV gene were 657.83 +/- 1.14, 538.53 +/- 5.29, 130.50 +/- 1.46, and 33.14 +/- 0.47, respectively, as assayed by cytometry. The correlation coefficients of the transcription of DPP IV gene and the adhesive, incursive and migratory ability of ovarian carcinoma cells were -0.987, -0.983, and -0.991, respectively; the correlation coefficients of the expression of DPP IV and those ability of cells were -0.959, -0.988, and -0.968; the correlation coefficients of the activity of DPP IV and those ability of cells were -0.952, -0.868, and -0.983.</p><p><b>CONCLUSION</b>There is a negative correlation between the expression of DPP IV gene and the adhesive and incursive capability of cells of ovarian carcinoma.</p>
